Accompanying drawing explanation
Fig. 1 is double spiral groove cooler construction schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in more detail:
As shown in Figure 1, double spiral groove refrigeratory of the present invention is made up of induction pipe 1, outlet 2, cylindrical shell 3, double spiral groove housing 4, end cap 5, double spiral groove housing 4 is assemblied in cylindrical shell 3, end cap 5 is assemblied on double spiral groove housing 4 end face, induction pipe 1, outlet 2 are assemblied on another end face of double spiral groove housing 4, are communicated with respectively with one of them groove of double spiral groove housing 4.
Described double spiral groove housing 4 is with the contrary helicla flute of upper and lower two rotation directions, double spiral groove housing 4 is assemblied in cylindrical shell 3, form the contrary and cooling working medium flow channel be interconnected in bottom of two rotation directions, for sealing cooling working medium flow channel on the end face that end cap 5 is assemblied in double spiral groove housing 4, isolated external heat radiation simultaneously.Induction pipe 1, outlet 2 are assemblied on the top of double spiral groove housing 4, are communicated with respectively with one of them cooling working medium flow channel of double spiral groove housing 4.Cooling working medium enters in a cooling working medium flow channel of double spiral groove housing 4 and cylindrical shell 3 formation along induction pipe 1, after arriving double spiral groove housing 4 bottom, flow in another cooling working medium flow channel by bottom interface channel, and along this cooling working medium passage reversed flow to top, flow out from outlet 2.
Double spiral groove refrigeratory of the present invention is installed in engine charge calotte or exhaust tail cone, and signal transmission apparatus is placed in the cavity that the inner periphery of double spiral groove housing 4 and end cap 5 formed.Cooling working medium flows in the passage that double spiral groove housing 4 is contrary with two rotation directions that cylindrical shell 3 is formed, the heat of absorption signal transmission equipment radiation at work, also absorb simultaneously extraneous to refrigeratory internal radiation heat, for controlling the operating ambient temperature of signal transmission apparatus.
